LUNA coughed up a huge chunk of blood.
She knew she couldn't stop the magic circle from activating, but she wanted to at least slow it down. Their allies weren't here yet, so she needed to buy them some time. But she wouldn't last long.
[The magic circle is too powerful even for me!]
Right now, she was suspended in the air above the plaza in the Royal Capital.
From there, she could see the glowing blue light around the capital. Unfortunately, it was invisible to the eye of normal people. Even average Mana users would find it hard to see the activated magic circle.
Only a witch and someone similar to her race would see it clearly.
[It's good that the plaza is empty, so no citizen would get accidentally hurt.]
